Every week, I organize 400 to 700 links into roughly 60 categories as part of my ongoing effort to learn about AI. This is my personal notebook, which I enjoy sharing with friends… a hobby and a labor of love, rather than a commercial publication or product.
If you arrived here through a search or shared link, this page collects the links I found for DeepSeek for the week ending September 4, 2026.
As part of my learning process, I like to automate the category covers. It gives me a chance to learn Python and APIs.
This week’s cover prompt was written using Claude Opus 4.7, and the image was generated using Nano Banana 2.1.
Category Cover Image Prompt: A psychedelic screen-printed gig poster of a giant sperm whale diving downward through swirling deep-teal ocean currents, its body tattooed with intricate op-art circuitry and glowing lime-green open-source bubbles rising around it, hand-lettered bold title DeepSeek arcing across the top in Fillmore-era revival lettering, electric magenta and acid orange ink layers on cream paper with slight registration offset, harvest moon and autumn leaves drifting through an ornate decorative border, flat screen-print texture, intricate linework.

Summary by Claude Sonnet 5.5 based on this week’s links:
- Harness goes open source: DeepSeek Harness and OpenAI's Codex harness are both open source now. Zhihu contributor 第欧根尼 argues the runtime may be the next AI platform. A follow-up post says DeepSeek Harness is still updating, with two alpha releases in late August.
- New V4 variants: DeepSeek-V4-Flash-Vision-Exp weights are out. DeepSeek-V4-Pro-0813 is live on CoreWeave Serverless Inference, described as 1.6T parameters with 1M context, and Nvidia published an NVFP4 version on Hugging Face.
- Cheap tokens and a benchmark yardstick: Teknium noted Anthropic's cache reads are still about 13x pricier than DeepSeek Flash. Agent Arena also keeps placing newer models against DeepSeek V4 Flash and V4 (High), as with Qwen3.8-Flash-Next and GLM-5.3-Flash.
This summary was generated by Claude Sonnet 5.5 to help you explore the links below. Rest assured, I select, organize, and check the links by hand in Google Sheets, and write the introduction and personal commentary in The Main Newsletters myself each week as a labor of love.
